a) There is another boat in the area, close enough to take the picture.
b) "it sprang out of the sea", meaning the other boat had to have the camera out, pointed at the boat, pressing the shutter at the moment the whale left the water.
c) No second or third pic of the whale on the boat seems to exist... why not if the person had their camera out, taking pictures?
d) There's one guy at the wheel, oblivious to the whale, yet the wife says they were watching it very close to the boat. What's up with that? Where's the wife?

It's a fake, sucked up by all the pseudo journalists, more interested in sensationalism than facts.
